In addition to massive personal wealth, the Teppers are known for their extensive philanthropy. Marlene Tepper is a member of the board of overseers at Rutgers University, where the couple donated $3.4 million to the Mason Gross School of the Arts, a gift that stipulated a $3 million endowed faculty chair. A decade ago, the Teppers donated $55 million to his alma mater, Carnegie Mellon, which was the largest gift ever to the school.

The two live in Livingston, N.J., and own a mansion in the Hamptons. They have three grown children.
